Recent advancements in metal–organic frameworks (MOFs) for flexible supercapacitors aimed at wearable technology

Abstract

Flexible supercapacitors have made significant progress, as they can be integral to the wearable technology field due to their unique ability to allow seamless movement for the wearer. Metal–organic frameworks (MOFs) with high surface area and exceptional porous structure exhibit greater potential in developing supercapacitor electrodes and have been widely explored. Hence, integrating MOFs for flexible supercapacitor wearable technology could harness high-efficiency wearable supercapacitors to explore various flexibility forms and impact practical applications. From this perspective, we critically investigate the recent developments in MOFs and MOF-based composite materials. Advancements in flexible supercapacitors are surveyed, and their electrochemical performance is overviewed. Furthermore, their pivotal role in enabling wearable technology to reach its full potential is emphasized. Finally, the associated challenges and opportunities of flexible supercapacitors are discussed in detail, highlighting the dominant significance of low dimensional MOFs for flexible supercapacitor solutions in evolving futuristic wearable technologies.
